Double-band antenna



The FIGURE is a front elevational view of a double-band antenna showing our new design.

The double-band antenna is so thin that it is indiscernible in rear, top, bottom and side views, and two portions of the antenna shown in the FIGURE are coplanar.

The broken lines in the FIGURE are included to show unclaimed subject matter only and form no part of the claimed design. Only the two shown portions of the antenna in the FIGURE are claimed. 

The ornamental design for a double-band antenna, as shown and described.
